摘　　要：同步发电机励磁系统是一个时变、非线性、强干扰、模型十分复杂的系统,应用传统的控制方法往往难于达到满意的控制效果。变论域自适应模糊控制具有对模型无准确要求、响应快速、精度高、鲁棒性好、适应性强等优点。将变论域自适应模糊控制器应用于同步发电机的励磁调节与控制中,首先详细地论述了控制器的结构设计、伸缩因子的选择方法,然后给出了具体的控制算法;最后给出的仿真结果表明该控制算法在同步发电机励磁控制中切实可行,效果令人满意。Excitation system of synchronous generator is a typical nonlinear and time-varying system with strong disturbance,high uncertainty and model complexity.It is difficult to achieve a good performance by traditional control methods.Adaptive fuzzy control method based on variable universe has the advantages such as no need for exact models,fast response,high precision and strong robustness.The variable universe adaptive fuzzy controller is applied to the excitation regulation and control of synchronous generator.Firstly,the corresponding structure design and the extension factor selection of the controller are provided in detail,and then the control law is given.Finally,the simulation results prove that the control scheme is reliable and effective.
